unreachable Sites

I have been notified this morning by several people that there is some websites that are unreachable from Haiti: http://www.hostcentric.com, http://www.gama.ht those are examples. It happens with different ISP. When we change th DNS using the google one 8.8.8.8 it's ok for some but some others still remain unreachable. Can some of you from the Nanog list check and advise?
